I have a manual transmission 2003 subaru legacy 2.5 gt. I can't determine if the noise is originating from the engine or the tires. When in motion I can hear something spinning. The noise gets louder in relation to increasing speed. When I decelerate it sounds like it is spinning faster than it should be. I had the drive shaft and clutch replaced as well the transmission rebuilt 6 months ago (long story). Like typical subarus it is all wheel drive. Steering wheel is shaking at 60 mph. Any ideas?
